将下列代码导入，并导入相关jar包，修改mysql连接配置即可

@SpringBootTest

    public static void main(String[] args) {
        //需要构建一个 代码自动生成器 对象
        AutoGenerator mpg = new AutoGenerator();
        //配置策略

        //1.全局配置
        GlobalConfig gc = new GlobalConfig();
        //获取到项目所在的绝对路径
        String projectPath = System.getProperty("user.dir");
        gc.setOutputDir(projectPath+"/src/main/java");
        gc.setAuthor("fuyu");
        gc.setOpen(false);//是否打开资源管理器
        gc.setFileOverride(false); //是否覆盖
        // 自定义文件命名，注意 %s 会自动填充表实体属性！
        gc.setServiceName("%sService");//去Service的I前缀
        gc.setIdType(IdType.ID_WORKER);
        gc.setDateType(DateType.ONLY_DATE);

        //4.策略配置
        StrategyConfig strategyConfig = new StrategyConfig();
        strategyConfig.setInclude("user"); //设置要映射的表名,若有多张表，逗号隔开即可
        strategyConfig.setNaming(NamingStrategy.underline_to_camel);
        strategyConfig.setColumnNaming(NamingStrategy.underline_to_camel);
        strategyConfig.setEntityLombokModel(true); //自动lombok
        strategyConfig.setLogicDeleteFieldName("deleted");
        
        //自动填充配置
        TableFill CreateTime = new TableFill("create_time", FieldFill.INSERT);
        TableFill UpdateTime = new TableFill("update_time", FieldFill.INSERT_UPDATE);
        ArrayList<TableFill> tableFills = new ArrayList<>();
        tableFills.add(CreateTime);
        tableFills.add(UpdateTime);
        strategyConfig.setTableFillList(tableFills);
        //乐观锁
        strategyConfig.setVersionFieldName("version");
        // controller类是否直接返回json
        strategyConfig.setRestControllerStyle(true);
        strategyConfig.setControllerMappingHyphenStyle(true);
        mpg.setStrategy(strategyConfig);
        mpg.execute();//执行
    }
